[0002] In the bone screw production process, raw material cutting is one of the key steps, and the shearing machine plays an important role. In bone screw production, high-speed precision shearing machines are often used for cutting bars or wires such as titanium alloys and stainless steel. It cuts the raw material by high-speed downward shearing, which has the characteristics of fast shearing speed and smooth cut. It can achieve efficient fixed-length cutting of metal raw materials with a diameter of less than 10mm. With the help of the transmission wheel set, it can complete automated continuous operation. For bone screw blank processing with high requirements for cutting accuracy and production efficiency, the shearing machine is one of the important equipment choices.

When adjusting the limiting distance, it is necessary to manually tighten the bolts repeatedly to loosen and adjust them before fixing them again. This operation is cumbersome and time-consuming, and the adjustment efficiency is low. In addition, traditional limiting structures are mostly rigid contact, which can easily cause surface damage due to excessive frictional resistance during wire transmission, affecting the quality of raw materials.

The operation is cumbersome and time-consuming, and the adjustment efficiency is low. In addition, traditional limiting structures are mostly rigid contact, and the wire material is prone to surface damage due to excessive frictional resistance during transmission, which affects the quality of the raw material.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown in the figure, the raw material cutting device for bone screw production provided by this utility model embodiment includes a body 1, a cutting end 2 and a transmission wheel set 3. The cutting end 2 is fixedly connected to the upper side of the front end inside the body 1. The transmission wheel set 3 is arranged on the rear side of the cutting end 2 and fixedly connected to the body 1. Boxes 4 are fixedly connected to the left and right sides of the rear end inside the body 1 respectively. Each of the two boxes 4 is provided with a quick limiting device 5. The quick limiting device 5 includes a clamping component 51, a linkage component 52 and a control component 53.

[0023] refer to Figure 1 , Figure 2 and Figure 3 There are two clamping components 51, which are respectively located on the left and right sides of the upper part of the box body 4. The linkage component 52 is located at the lower end of the two clamping components 51, and the control component 53 is located at the lower end of the linkage component 52.

[0024] The above solution is adopted: by setting up a quick limit device 5, the wire is limited to prevent it from running off-center when it is conveyed by the transmission wheel group 3. It can quickly adjust the limit according to the radius of the wire, eliminating the trouble of repeatedly tightening the bolts to adjust the limit plate limit distance, and making it easy to adjust the limit.

[0025] refer to Figure 3 and Figure 4 Support rods 6 are provided on the front and rear sides of the upper part of the box body 4, and the left and right ends of the two support rods 6 are fixedly connected to the left and right sides of the inside of the box body 4, respectively.

[0026] The above solution is adopted: support rods 6 are respectively set on the front and rear sides of the upper part of the box 4 to support and limit the movement of the two clamping components 51, so as to ensure the stability of the movement of the moving seat 511.

[0027] refer to Figure 2 , Figure 3 and Figure 4 The clamping assembly 51 includes a movable seat 511, a clamping frame 512, a pressure rod 513, and rolling elements 514. The movable seat 511 is sleeved on the right end surface of the two support rods 6 and is slidably connected to the support rods 6. The upper ends of the front and rear sides of the movable seat 511 extend out of the box body 4 and are movably connected to the box body 4. The clamping frame 512 is located on the upper right side of the box body 4 and is fixedly connected to the upper end of the movable seat 511. The pressure rod 513 is fixedly connected to the lower surface of the movable seat 511. The number of rolling elements 514 is several and they are evenly arranged inside the clamping frame 512.

[0028] The above solution is adopted: by setting up clamping components 51, the wire material is clamped, and the clamping of the two clamping components 51 is used to limit the wire material.

[0029] refer to Figure 3 and Figure 5 The linkage component 52 includes a limiting slide rail 521, a moving plate 522, and an extrusion groove 523. There are two limiting slide rails 521, which are fixedly connected to the left and right sides of the lower inner surface of the box body 4, respectively. The moving plate 522 is sleeved on the upper surface of the two limiting slide rails 521 and is slidably connected to the limiting slide rails 521. There are two extrusion grooves 523, which are respectively opened on the left and right sides of the upper surface of the moving plate 522 and both penetrate the moving plate 522. The lower ends of the two pressure rods 513 extend into the two extrusion grooves 523 and are movably connected to the extrusion grooves 523.

[0030] The above solution is adopted: by setting up a linkage component 52, the clamping component 51 is driven. The two clamping components 51 are driven to open and close synchronously by the squeezing cooperation of the two squeezing grooves 523 and the two pressure rods 513.

[0031] refer to Figure 3 and Figure 5 The control component 53 includes a lead screw 531 and a motor 532. The lead screw 531 is located at the lower end of the inside of the box 4 and passes through the moving plate 522 and is threadedly connected to the moving plate 522. The front end of the lead screw 531 is rotatably connected to the front end of the inside of the box 4. The motor 532 is fixedly connected to the rear side of the lead screw 531 and is fixedly connected to the lower surface of the inside of the box 4.

[0032] The above scheme is adopted: by setting up a control component 53, the quick limit device 5 is driven and controlled. The screw 531 and the moving plate 522 are threaded together to drive the moving plate 522 to move back and forth. Then, the two clamping frames 512 are adjusted to clamp by the pressing cooperation between the pressing groove 523 and the two pressure rods 513.

[0033] refer to Figure 2 , Figure 3 and Figure 4 The rolling element 514 includes a rotating shaft 5141 and a rubber roller 5142. The rotating shaft 5141 is disposed inside the clamping frame 512, and its upper and lower ends are rotatably connected to the upper and lower surfaces inside the clamping frame 512, respectively. The rubber roller 5142 is sleeved on the surface of the rotating shaft 5141 and is rotatably connected to the rotating shaft 5141. The left side of the rubber roller 5142 extends out of the clamping frame 512 and is movably connected to the clamping frame 512.

[0034] The above solution is adopted: by setting a rolling element 514, the wire is assisted in moving when it is clamped and limited, so as to avoid the wire being difficult to move due to clamping, and the clamping and limiting are synchronized without affecting the normal movement of the wire during cutting.

[0035] The working principle of this utility model:

[0036] When the limit is reached, the wire is placed between the two clamping frames 512. The motor 532 is started to drive the lead screw 531 to rotate. The lead screw 531 is threadedly connected to the moving plate 522, which drives the moving plate 522 to move back and forth linearly along the limit slide rail 521. When the motor 532 rotates forward, the moving plate 522 moves forward and when it rotates backward, it moves backward. When the moving plate 522 moves backward, it drives the two extrusion grooves 523 to move. The inner walls of the two extrusion grooves 523 move and extrude the two pressure rods 513. The two pressure rods 513 are extruded and drive the two moving seats 511 to slide together horizontally along the support rod 6. The clamping frame 512 moves synchronously and drives the several rolling parts 514 on both sides to move to clamp and limit the wire. The rubber roller 5142 is rotatably connected to the rotating shaft 5141. When the wire is transmitted, the rubber roller 5142 rotates freely around the rotating shaft 5141 to reduce frictional resistance and avoid damage to the wire.

[0037] When the clamping limit is released or the clamping distance is increased, the motor 532 reverses and drives the lead screw 531 to increase in the opposite direction, which in turn drives the moving plate 522 to move forward. The moving plate 522 moves forward and drives the two extrusion grooves 523 to move. At the same time, it extrudes the two pressure rods 513 to move outward and extrude. This causes the two pressure rods 513 to drive the two moving seats 511 to move away from each other on the surface of the support rod 6. This, in turn, causes the clamping frame 512, which is fixedly connected to the moving seat 511, to move away from each other, thereby releasing the clamping limit or increasing the clamping distance.

[0038] In summary, the raw material cutting device for bone screw production, through the coordinated use of a machine body 1, cutting end 2, transmission wheel set 3, box 4, quick limiting device 5, clamping assembly 51, moving seat 511, clamping frame 512, pressure rod 513, rolling element 514, rotating shaft 5141, rubber roller 5142, linkage assembly 52, limiting slide rail 521, moving plate 522, extrusion groove 523, control element 53, lead screw 531, motor 532, and support rod 6, improves or solves to some extent the problem of existing cutting machines using multiple manually twistable bolts to fix the limiting plate to limit the wire material. When adjusting the limiting distance, it is necessary to manually and repeatedly twist the bolts to loosen the fixation, adjust, and then fix it again, which is cumbersome, time-consuming, and inefficient. In addition, traditional limiting structures are mostly rigid contact, and the wire material is prone to surface damage due to excessive frictional resistance during transmission, affecting the quality of the raw material.
